| Abstract: | According to Lambert-Beer's Law, 12 kinds of forms of isoflavones molar absorptivity as the standard, use UV spectrophotometry to make the content of the total isoflavone content of soybean sauce cake and soybean isoflavones products. The results showed that the determination data were reliability and accuracy comparing with the three-wavelength ultraviolet, high performance liquid chro matography, gas chromatography. And the advantage is no standard samples reducing research uses, and the method is simple and practical. |
| Keywords: | Lambert-Beer's Law molar absorptivity soybean isoflavones |
